ATONHZER.

SPECIFICATION forming part of Letters Patent No. 661,313, dated November 6, 1900.

Application filed June 25,1897. Serial No. 642,664. (No model.)

T0 (all wtont ft Htcty concern:

Be it known that I, OLIN Q. HOLMAN, a citizen of the United States, and a resident of La Grange, in the county of Cook and State of Illinois, haveinvented certain newand useful Improvements in Atomizers, of which the following is a specification.

This invention relates to improvements in atomizers, and relates particularly to atomizers of the type comprising a plurality of bottles or flasks in controlled communication with an air-compressor or other atomizing medium and connection between said bottles or asks whereby the contents of any two or more of said bottles or flasks in a vaporous state may he thoroughly mixed or intermingled before being discharged from the apparatus.

The object of my invention is to provide an atomizer of this type which shall be efcient in its operation and of simple construction.

To this end the invention consists of the various features, combinations of features, and details of construction hereinafter described and then pointed out in the claims.

In the accompanying drawings an atomizer embodying my invention is fully illus trated.

Figure l is a perspective View of my improved atomizer, illustrating the method of operating' the same. Fig. 2 is atop plan view thereof, partly in section. Fig. 3 is a vertical sectional view thereof on the line 3 3 of Fig. 2, and Fig. et is a sectional View of a preferred form of atomizing-tube.

An atomizer embodying my invention comprises a chamber A, the interior of which communicates with an air-compressor (not shown) by a pipe or tube a. The chamber A is preferably provided with a pressure-gage A', adapted to indicate the pressure in said chamber, and the pipe or tube a is controlled by a valve a', which affords convenient means for regulating the pressure in the chamber A. Both the gage A and the valve a may be of any desired or approved construction.

My improved atoinizer also comprises a series of bottles or flasks B, adapted and designed to contain medicines in liquid form7 the interiors of which are connected with the interior of the chamber A by tubes B', which comprise sections h IJ', of which the sections l) extend to the mouths of the bottles or flasks B, and the sections b', which are preferably made detachable, extend into the bottles or iiasks B and below the surface of the medicine contained therein and are adapted to atomize or vaporize the contents of said bottles or flasks when air under pressure is discharged therethrough. Each of the tubes B is controlled by a suitable valve or stop-cock B2. For purposes of convenient reference the tubes B will hereinafter be designated as atomizing-tubes. The sections b of said tubes B' may be of any usual or approved coustruction to effect the reduction ot' the liquid contents of the bottles or asks B to vapor-ous form. In the preferable construction shown, however, longitudinal holes or openings b2 b3, Fig. 4 of the drawings, are formed in the up` per and lower ends of said sections b, respectively, of which the holes or openings b2 communicate with transverse holes or openings h4, and the holes or openings b3 communicate with diagonal holes or openings b5, which conneet the holes or openings b with the transverse holes or openings Il on opposite sides of the holes or openings b2. As shown, the discharge-openings of the transverse holes or openings h4 and of the diagonal holes or openings 195 coincide with each other. In the preferable construction shown also the holes or openings b2 are materially larger than the transverse holes or openings b4, and the discharge ends of said holes or openings b2 are contracted to about the size of said transverse holes or openings h4.

To facilitate the construction of the sections b', they are made in two parts, the upper part being secured in a suitable socket formed in the lower part by engaging screw-threads- The holes or openings b2 are formed in the upper parts of said sections b', extending entirely through the same and being of uniform diameter throughout, and the holes or openings b3, h4, and b5 are formed in the lower parts of said sections ZY. The contraction of the holes or openings h2 is effected by partially closing the inner ends of the sockets in the lower parts of said sections h', leaving holes or openings of desired size therein which connect said holes or openings b2 with the holes or openings b4.

An atomizer embodying my invention also ICO comprises a dischargetube C, the interior of which is in direct and open communication with the interiors of all oi' the bottles or flasks B. The ends of the tube C are closed, and said tube is provided with a discharge-opening c.

In the preferable construction shown the elements of the atomizer are supported upon a standard D, which is secured in upright position in a foot or base D. The chamber A is supported directly upon said standard, while the bottles or flasks B are supported upon suitable arms which project laterally from said standard D. As shown,said arnis are tubular and form the sections ZJ of the atomizing-tubes B. As preferably constructed also my improved atomizer comprises heads E, secured to the ends of the sections b of the tubes B. On the under sides of said heads are formed sockets e, in which the bottles or flasks B are secured, preferably by means of engaging screw-threads, vand secured in said heads, so that they will extend into the said bottles or flasks, are the atomizing-sections b of the tubes B. Formed in said heads E are transverse openings in which the discharge-tube C is supported, said heads being soldered or sweated upon said tube to insure a tight joint. Passage-ways e are also formed in said heads E, which connect the adjacent ends of the sections b b of the atomizingtubes B'. Preferably, also, the seats for the stop cocks B2, which control the passage through the tube B, are formed in said heads E, as clearly shown in the drawings.

The operation of my improved atomizer will be readily understood without a detailed description thereof.

1. In an atomizer, the combination with a plurality of medicine flasks or bottles, an airchamber provided with an air-supply opening, atomizing-tubes which connect said airchamber with said flasks or bottles, valves which control said atomizing-tubes and a discharge-tube from said flasks 0r bottles, of a standard upon which the elements of said atomizer are supported, the air-chamber being formed in said standard and the flasks or bottles and the discharge-tube being supported on tubular arms secured in the walls of said air-chamber, said tubular arms forming sections of the atomizing-tubes, substantially as described.

2. In an atomizer, the combination with a plurality of medicine flasks or bottles, an airchamber provided with an air-supply opening, atomizing-tubes which connect said airchamber with said flasks or bottles, valves which control said atom izing-tubes, and adischarge-tube from said flasks or bottles, of a standard upon which the elements of the atomizer are supported, the air-chamber being supported directly upon said standard and the flasks or bottles and the discharge-tube on tubular arms secured in the walls of said air-chamber, said tubular arms forming sections of the atomiZing-tubes, substantially as described.

3; In an atomizer, the combination with a plurality of medicine flasks or bottles, an airchamber provided with an air-supply opening, atomizing-tubes which connect said airchamber with said fiasks or bottles, valves which control said atomizing-tubes, a pressure-regulating valve anda pressure-gage applied to said air-chamber and a dischargetube, which communicates directly with said ilasks or bottles, of a standard upon which said elements are supported, the air-chamber being supported directly upon said standard and the tlasks or bottles and the dischargetube on tubular arms secured in the walls of said air-chamber, and radiating therefrom, said tubular arms forming sections of the atomizing-tubes, substantially as described.

LL. A spray-tube provided with an air-passage extending` downward from the upper end, a liquid-passage extending upward from the lower end, an intervening partition and [ine outlets from the proximate ends of these two passages converging to a spray-hole, the said hole and converging outlets being all within the outer surface of the external cylindrical wall of the said tube and obviating the need of a lateral nozzle or other projection or projections, from the side of the said tube, substantially as set forth.

5. A spray-tube provided with an air-passage extending downward from the upper end, a liquid-passage extending upward from the lower end, an intervening partition and line outlets from the proximate ends of these two passages, converging to a spray-hole, the liqudoutlet being inclined upward and the airoutlet approximately horizontal in order that the liquid may be blown upward obliquely in the act of vaporization and finely divided, substantially as set forth.

In testimony that I claim the foregoing as my invention I have hereunto set my hand this 25th day of June, 1897.
